Hi Laurent, Thanks for the feedback, I've uploaded the repository with the missing method but I cannot reproduce the crash in Windows. Have you unmangled every function name tested? Are you running just the Z3950FFILibraryTest? Notice the Z3950FFIServerLibraryTest tests are performed against a Z39.50 server running in local host, otherwise will fail (however that shouldn't crash the VM), so you may want to run only the Z3950FFILibraryTest suite. If you or anyone want a local Zebra server for Win32 - although most configuration files should work with other platforms - for testing purposes please let me know.
Does the Kant test crash the VM too? Z3950Client new server: #Acadia; query: ( Z3950Query new author: 'Kant' ). (see http://67.222.12.200:8889/WebOpus/52 for sample successful results) I will set up a Linux box tomorrow and try to reproduce there.
